comemso launches Easy Chester Micro portable tester for AC charger and ISO 15118-2 communication checks
By Eve
German test-equipment maker comemso has launched the Easy Chester Micro, a 5.4 kg portable tester rated IP 66 when closed, combining charging and communication tests with optional safety tests for AC wall boxes and charging stations. It simulates the vehicle to IEC 61851-1 and SAE J1772, measures Control Pilot voltage, PWM duty cycle and Proximity Pilot values, and sets up ISO 15118-2 communication without an external protocol converter, with a 10.1-inch touchscreen guiding users and no laptop or customer vehicle needed. The report notes that since 8 January 2026 the EU's AFIR has required new or renovated public charging points to comply with EN ISO 15118-1 to 5, and the ISO 15118-2 test also checks the station's powerline communication chip and link to the vehicle.
Why it matters
With AFIR requiring ISO 15118 compliance on new or renovated public points, CPOs and installers need a way to verify communication at commissioning and during maintenance without tying up a vehicle. A single portable tool covering inspection, repair and periodic checks could simplify service workflows and acceptance testing in procurement specifications.

Openreach and Allstar expand home, public and shared depot charging for 7,000 electric vans
Openreach has partnered with EV payment specialist Allstar to widen charging access for its 7,000-strong electric van fleet, where around one in three engineers cannot charge at home. Allstar Homecharge pays work-related home charging costs directly to drivers' energy suppliers, while public charging is being concentrated through fewer strategic charge point operators and Allstar Co-Pilot helps engineers find approved locations. The partnership is also developing commercial and shared depot access through partners including First Charge and Voltempo, offering larger bays, high-speed charging and bookable slots payable with existing cards such as Allstar Chargepass.
Why it matters
A large UK fleet is consolidating public charging onto fewer operators and seeking depot sites with larger bays and bookable high-speed charging, which signals what fleet buyers will favour in procurement. Operators serving commercial vehicles with card-based payment and booking have a clear route into this demand.
TellusPower and Zūm deploy bidirectional chargers for US electric school bus fleets
TellusPower is supplying bidirectional chargers to transportation-as-a-service startup Zūm, which is credited with deploying the first fully electric school bus fleet in the US, a 75-strong fleet in Oakland Unified School District for the 2024 to 25 school year. A more recent project with San Francisco Unified School District uses the same hardware, which Zūm white-labels. TellusPower CEO Mike Calise told EV Infrastructure News that the chargers act as a "power router", linking idle bus batteries with the grid, buildings and battery storage for up to 5MW of theoretical cumulative capacity.
Why it matters
Fleets with fixed duty cycles, such as school buses and refuse trucks, are being positioned as dispatchable energy assets, which could change how depots are specified and how bidirectional hardware is procured. The white-label arrangement also shows hardware vendors reaching the market through fleet service providers rather than selling direct.
Moto reports 96% customer satisfaction across its motorway services network
Independent research found satisfaction across Moto's network reached 96%, up from 94% in 2023 and 93% in 2022, while 95% of all visitors to motorway services were fairly or very satisfied. Five Moto sites (Rugby, Sawtry, Kinross, Pease Pottage and Donington Park) scored 99%, and the lowest scoring sites reached 90%. Moto CEO Ken McMeikan said the company has invested more than £260 million in its services over the last five to six years.
Why it matters
Motorway service areas are key host locations for rapid and ultra rapid charging, and sustained operator investment in site quality shapes the dwell experience that charge point operators rely on. The figures give procurement teams a benchmark when assessing host partners, though the excerpt provided does not detail the charging element.
